Answer:
A common characteristic of most Alkali Metals is their ability to displace H2(g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions. The general reaction of an alkali metal (M) with H2O (l) is given in the following equation:2M(s)+2H2O(l)⟶2M+(aq)+2OH−(aq)+H2(g)(1)
Explanation:
Answer:
A) 12 mol H2O.
Explanation:
Hello,
In this case, for the given reaction:

We notice that oxygen is in a 7:6 molar relationship with water, for that reason, the resulting moles of water turn out:

Thus, the answer is A) 12 mol H2O.
